So I spent a better part of today trying to diagnose a network cable run that was not working. I was getting conflicting information with my tester measured from either end of the cable.

I had to go above the drop ceiling, in between the insulation and this is what I pulled out. Boy does it suck being up there. Now I'm itchy all over the place. But at least I think I see the problem. What's the bend radius of network cable again?

This is also known in inner networking circles as the full-double-twist (FDT). Twisting it like that greatly increases the magnetic field, thereby doubling the effective bandwidth. This was by design. In fact cables like this often transmit so much data and become so hot that they are best cooled by liquid nitrogen. Their use can be most effectively realized in a modern token ring network where the banana flux capacitance (BFC) has the ability to flow freely through FDT pair cabling. Little-known fact: FDT was first used in the construction of the original Deathstar.

You may need to be careful, some people are very gullible. To this day, I cannot convince my boss that the 2x gigabit links between our main switches does not equal a 4Gbps connection. 2 x 1 = 4 according to him.

You can get that kind of throughput if you implement them in a FDT, just saying :)

Pfft. Token ring is still far too futuristic. I don't expect to see fully utilized Token ring for another 10 years. minimum.

I had to redo a run about a year and a half ago - 100yr old building so wire had to go outside the building and up the side into the attic - as it exited the building, it was splayed open, fully exposed to the elements, with each wire untwisted a few inches and spliced with orange wire nuts. Amazing it worked at all - but the system had to be reset daily.

Re-ran it inside conduit and one-piece end-to-end - went from failing daily to running reliably for over 18 months.
